Hollywood Matchmaker: Julianne Hough

Why it could work: 25-year-old Zac is much closer to Julianne's age than Ryan was, so the two actors may be more in sync in terms of where they are in their lives and careers. Since we can't pair Julianne with Josh Duhamel (such a tragedy), "Lucky One" hunk Zac may be perfect for our leading lady. Also, Julianne has said: "It would be fun to dance with somebody who has rhythm like Zac. He is young and I'm sure he can move."
